My electric sad iron includes the usual sole plate 11 which is electrically heated by a heating element 17 embedded in the sole plate. A metal shell 12 in inverted position is mounted over the sole plate in the usual manner. Within the metal shell 12 is a water reservoir 13 used for storing water within the space between the shell 12 and the sole plate 11. At the forward portion of the reservoir 13 there are splash bafile plates 13A. A molded plastic handle member 14 is mounted over the shell 12 in the usual manner. The shell 12 and sole plate 11 are interconnected by two screw bolts 15, only one of which is shown in the drawing. The shell 12 and handle member 14 are interconnected by screw bolts 16. The molded plastic handle member 14 is made of one of the usual and commercially available plastic materials utilized for devices of this kind. It is an electric insulator and heat insulator as well and is adapted for the purpose of providing the superstructure or handle of an electric sad iron. The material, however, is subject to deterioration upon being exposed to steam and hot water. It has been a problem in the use of the commercially available plastic materials that the handle member would crack, decompose and generally deteriorate after repeated subjection to contact with steam and hot water. One of the objects of the present invention is to avoid the difiiculties of this undesirable characteristic of such commercially available molded plastic materials.

Carried by the sole plate 11 under the reservoir 13 is an adjustable thermostat assembly denoted generally by the reference character 18. Wires 19 connect the themostat with a heating element 17. Lead-in wires 20 adapted to be connected to a source of electrical energy enter the handle member 14 in the usual manner and are joined with the wires 19 and heating element 17 by leads not shown.

Disposed near the forward end of the sole plate 11 is a steam generating chamber 21 which is provided by a depression in the sole plate cove-red by a gasket 30 and a cover plate 29 extending over the sole plate. The steamgenerating chamber 21 is in communication with conduits extending around through the sole plate to a duct 22 having a plurality of orifices extending through the bottom of the sole plate 11. The arrangement is such that steam gene-rated in the chamber 21 is emitted or discharged out through the orifices in the bottom of the sole plate supplied thereto by interconnecting ducts or conduits.

In order to facilitate the ready ascertainment of the current level of the water in the reservoir 13, I provide a transparent sight member 73, made of glass or clear plastic, into which water in the reservoir may enter when the iron is up-ended, that is, rested on its heel and pointed upwardly as when the iron is not being used in its normal horizontal position. The sight member 13 is cup-shaped or tubular with its lower end open and upper end closed, thus providing a recess 73D.

There are aligned openings in the top wall of the reservoir 13, in the top wall of the shell 12, and in the lower horizontal portion of the plastic handle member 14 disposed over the shell 12. The sight member 73 extends axially through these aligned openings as shown. The sight member 73 has an integral annular flange 73A extending therearound and protruding radially outwardly theref om. Extending upwardly from the flange 73A on diametrically opnosite sides thereof is a pair of bosses or protrusions 73B and 73C.

A resiliently yieldable gasket 74 of silicone rubber is provided for effecting a watertight seal between the sight member 73 and the wall of the reservoir 13. This or variations in manufacture and assembly are accomgasket 74 has a cylindrical portion 74B slightly tapered which fills the space between the outer wall of sight member 73 and the edge of the opening in the top wall of reservoir 13. The edge of the opening in the reservoir wall is turned or flanged downwardly as shown for accommodating and engaging the cylindrical portion 74B of the gasket. The gasket 74 has a flange portion 74A which extends outwardly and is positioned between the bottom side of flange 73A of the sight member 73 and the opposed upper side of the top wall of reservoir 13.

The arrangement and dimensions of the parts are such that the bottom portion of the handle member 14, when the iron is assembled and bolted together, presses downwardly on the top of the bosses 73B and 73C extending from the flange 73A. This causes the flange 73A to press down firmly on, and to slightly compress, the gasket 74 and to thus assure a watertight seal between sight member 73 and the wall of the reservoir 13.

The bosses 73B and 73C are arranged on opposite lateral sides of the sight member, that is, along a line disposed transversely of the iron. In this manner, a good firm engagement is made between the plastic handle member 14 and the sight member 73, notwithstanding a lack of precise parallelism between flange 73A and the bottom side of handle member 14. Inevitable tolerances modated for by the arrangement.

The top of the sight member 73 carries indicia 73E, such as a line and marking as shown, for indicating a preferred water level and with which the actual water level may be visually compared when the iron is upended. The arrangement fulfills a desired object of a reliable, eflicient and economical means for indicating current water level.

Formed in the molded plastic handle member 14 is an upright open space or dome 24, and extending forwardly from this dome 24 is an inlet or fill opening 23. Lining the upright open space or dome 24 is a metal liner 25. This liner 25 entirely covers the interior wall surface of the open space or dome 24 and also extends downwardly through an opening in the upper wall of the reservoir 13 so as to communicate with the reservoir 13. The fill opening 23 is also lined with a metal tube 26 so as to protect the plastic material of the wall of the opening. The arrangement is such that the metal of tube 26 and liner 25 protects the plastic material from contact with steam or hot water. There is a metal concave cup member 27 covering the forward portion of the plastic material of the handle member 14 and so disposed as to lead into or form a tunnel for the metal tube 26. Upon the iron being tipped upright, water poured downwardly against the cup member 27 and into the inlet opening 23 flows down and into the liner 25 of the dome 24, and thence downwardly into the reservoir 13 to fill the same. The metal of the member 27, tube 26 and dome liner 25 is of a suitable character, such as to resist corrosion and adverse effect from steam and hot Water and thereby protect the plastic material.

A washer or seal member 28 of silicone rubber is positioned between the top wall of the shell 12 and the top wall of the reservoir 13 and around the liner 25 so as to provide a seal at that location.

Extending through an opening in the flat cover plate 29 and gasket 30 above the steam chamber 21 is an internally threaded bushing 31 of brass or other suitable material. This bushing 31 extends downwardly into the steam chamber 21 and has an outwardly turned flange 31A at its lower end disposed within the steam chamber 21. Details of this are shown in FIGURES 4 and 5. To better insulate the bushing 31 from the plate 29 and to resist the passage of heat from the plate 29 enclosing the steam chamber 21, there are utilized a plurality of washers 32, 33, 34 and 35. Washers 32 and 33 are above the plate 29 and washer 35 is below the gasket 30 and above the flange 31A. The centering washer 34 surrounds the part of the bushing 31 that is within the hole provided therefor in the plate 29 and gasket 30. The washers 32, 33 and 35 are of fiber glass bonded with a suitable resin and are particularly suited to insulate the bushing 31 from the plate 29 and gasket 30. The can-1 tering washer 34 is of a suitable silicone rubber and is also adapted to insulate the bushing 31 so as toresist the passage of heat therefrom. ing 31 is so mounted that a minimum of heat from the steam chamber 21 is passed upwardly therethrough.

A valve seat cage member 36 is threadably engaged in the bushing 31, the threaded portion 36D being threaded to the internal threads in the bushing 31. The valve seat.

cage member 36 is made of brass or other suitable material. The cage member 36 stands uprightly in the reservoir 13 over the bushing 31 and it has longitudinally ex-. tending slots 36A to permit water in the reservoir to free- 1y enter the interior of the cage member 36. At the bottom part of the cage member 36 there is a valve seat portion 36B having a restricted opening therethrough. Ex-

tending downwardly from the valve seat portion 36B is.

a lower portion 36C which protrudes downwardly into the steam chamber.

Mounted within the cage member 36 to move 1ongi-.

tudinally thereof is a movable valve member 38. This valve member 38 has a rounded valve surface 38A adapted to seat on and sealingly engage with the valve seat 36B. Extending downwardly from the valve surface 38A is a guide pin portion 38B which moves up and down within the lower portion 36C. The valve member 38 has a shoulder portion 38C as shown, and extending upwardly from the shoulder portion 38C is an upper portion 38D. The valve member 38 is resiliently urged upwardly so as to open the orifice around the valve seat 36B by a coil spring 39 which pressesupwardly on the shoulder portion 38C and downwardly on the bottom wall of the cage member 36. The bias of the spring 39 is such that it may be overcome so as to move the valve member 38 downwardly to cause the valve surface 38A to seat on the valve seat 36B. The valve member 38 is restrained within the cage member 36 by an abutment. washer 40 against which the shoulder portion 38C may abut when in its upper position. A peened-over portion 36E of the cage member 36 holds the abutment washer 40 in position. A sealing member 37 seals the cage member 36 from the wall of the reservoir 13.

The upper portion 38D of the valve member 38 is positioned within a tube guide 41 disposed in an upright position. Extending downwardly into the upper end of the tube guide 41 is an upper rod member 42. This upper rod member 42 has a rounded upper end 42A. Surrounding the rod 42 is a coil spring 70. The lower end of the spring 70 resiliently presses downwardly on the top of the tube guide 41 and the upper end of the spring 70 is secured by a suitable washer and groove arrangement to the rod 42 so as to urge the rod 42 upwardly. This coil spring 70 is biased to resiliently urge the tube 41 downwardly. The coil spring 70 is stronger than the coil spring resistance of the spring 39. The spring 39 will yield and permit the valve 38 to move downwardly under the force of the tube 41 before the coil spring 70 yields. Therefore, in the first stage ofmovement of the rod 42 downwardly, the coil spring 39 yields and thereafter the coil spring 70 yields. It is to be noted that there is not a rigid or fixed interconnection between rod 42 and valve member 38 and they are always resiliently urged apart. This prevents rattling and loose shaking of parts which would otherwise occur but for the resilient urging of the rod 42 and valve member 38 apart in cooperation with the springs 39 and 70. It also compensates for manufacturing variations of the components.

In this manner,,the bush-.

A rotatable dial member 45 of suitable molded plastic material is mounted on a pivot pin 49 disposed on a vertical axis. A regulating lever 50 is swingable in a horizontal plane and is keyed to the dial member 45 so that upon the forward exposed end of the lever 50 being swung in an arc, the dial member 45 is correspondingly rotated. The dial member 45 on its lower surface has generally two cam surfaces. There is a cam surface engaged by the rounded upper. end 42A of the rod 42. The horizontal flat portion of this cam surface has been designated by the reference character 46 and the inclined portion at about a 45-degree angle thereto has been designated by the reference character 47. The bias of the coil spring 70, connected at its upper end to the rod 42, is such as to resiliently urge the rounded end 42A upwardly against the dial member 45. In the major portion of the rotative positions of the dial member 45, the rounded end 42A engages the flat horizontal cam surface 46. However, upon rotation of the dial member 45 to the end of the flat surface 46, then the rounded end portion 42A cammin-gly rides up on the inclined cam surface 47 and thus permits the rod 42 to move upwardly from its normal lower position. When the rounded upper end 42A is in engagement with the flat horizontal cam surface 46, the rod 42 is held downwardly and the resilience of the springs 39 and 70 and the arrangement of parts are such that the valve member 38 is positioned in its lower position illustrated in FIGURE 5 so that the opening at the valve seat 36B is closed. However, upon the rounded upper end 42A moving upwardly along the inclined surface 47 to its uppermost position, then the valve parts assume the position illustrated in FIGURE 4. Therefore, when water is to be admitted to the steam chamber 21 from the reservoir 13, the dial member 45 is turned so as to permit the rod 42 to move upwardly and hence permit the valve member 38 to move upwardly to the position illustrated in FIGURE 4. At other times, when steam is not to be generated, then the dial member is rotated so that the valve member assumes the position illustrated in FIG- URE 5.

Also carried on the lower part of the member is a cam surface 48 which is spaced radially outwardly from the axis of the dial member 45 more than are the cam surfaces 46 and 47 followed by the rounded end 42A. The cam surface 48 is irregular and has a profile designed for the desired setting of the thermostat assembly 18. A cam follower 54 carried by a yoke member 53 follows and moves up and down the irregular cam surface 48 designed for the thermostatic setting. The yoke member 53 embraces or extends around the dial member 45 so as to position the cam follower 54 on the side of the dial member carrying the cam surface 48. This yoke member 53 is pivotally carried on pivot pins 52 which, in turn, are carried by a bracket support 51 secured to the plastic material of the handle member 14 at a location on opposite sides of the rod 42. Ears 51A extending up from the bracket support 51 carry the pivot pins 52 upon which the yoke member 53 is pivotally carried. The pivot pins 52 are on a common horizontal axis.

The rearward end of the yoke member 53 is connected by a connection member 55 to a clevis device 56 which is threadably engaged with the upper threaded end of a rod 57 disposed in an upright position. The lower end of the rod 57 is connected by a lower connection device 58 to the adjustable leaf or part 59 of the thermostat assembly 18. Thus, upward and downward movement of the rod 57 changes the position of the adjustable part 59 of the thermostat assembly. The rod 57 is moved up and down by the swinging of the yoke member 53 on the pivot pins 52 in response to the positioning of the cam follower 54 by the cam surface 48. The bias of the parts is such that cam follower 54 is urged upwardly against the cam surface 48. Therefore by the swinging of the lever 50 to rotate the dial member through a portion of its arcuate path, the setting of the thermostat may be adjusted. The

disposition of the inclined cam surface 47 relative to the cam surface 48 is such that the inclined surface 47 be comes functional at one end of the arcuate travel of the lever 50. During the major portion of the travel of the lever 50, the thermostat is being adjusted while only when the lever approaches its extreme position does the inclined surface 47 become positioned to engage the rounded end 42A and thus actuate the valve member 38.

A tube 60 extends through the reservoir 13 and around the rod 57 so as to permit the rod 57 to move through the reservoir 13 but without leakage from the reservoir.

Extending upwardly from near the bottom wall of the reservoir 13 and up through the upper wall of the reservoir is a tube 61. This tube 61 extends through the sealing member 28 and through an opening in the shell 12, and upwardly into the handle member 14 as illustrated. The upper end of the tube 61 engages in a valve seat member 71 carried by the handle portion 14 as shown. A ball check 62 within the valve seat 71 permits water to move upwardly through the tube 61 but prevents water from moving downwardly from the valve seat member 71 into the tube 61. Secured to and extending upwardly from the valve seat member 71 is a rubber bellows 63 of elongated accordion type. A coil spring 64 within the bellows 63 resiliently urges the bellows 63 to an expanded condition. A rubber tube 65 provides communication between the lower end of the bellows 63 with a nozzle denoted generally by the reference character 66. The detailed structure of the nozzle 66 is illustrated in FIGURE 3. An orifice 67 in the nozzle 66 is directed forwardly so that Water may be sprayed forwardly of the iron upon fabrics being ironed. Within the nozzle 66 is a spring-biased ball check 68 which permits water to be discharged from the nozzle upon water under pressure being admitted to the nozzle from the tube 65. Positioned in the nozzle 66 is a deflector 72 which meets the stream of water entering it and breaks it up into a fine spray for emission from orifice 67. Adjacent the nozzle 66 and to one side thereof is an illuminating light denoted generally by the reference character 69.

Disposed over the bellows 63 is a key-board pressing member 43 which is spring-biased upwardly by a leaf spring 44. The arrangement is such that upon the operator pressing downwardly on the forward end of the member 43, the bellows 63 is compressed against the bias of the leaf spring 44 and the coil spring 64. Upon the bellows 63 being contracted, water therein is forced outwardly through the tube 65, and out through the orifice 67 of the nozzle 66. The ball check 71 prevents water in the bellows 63 from reentering the tube 61. Upon release or upward movement of the member 43, the bellows 63 is again expanded and by reason of the disposition of the ball check 68 and valve seat 71, water is sucked up from the bottom of the reservoir 13 through the tube 61 into the bellows 63 ready for another spraying operation.

In the event it is desired to omit the spraying function from an iron having the same general construction, the bellows, water tube and nozzle may be omitted and in place of the keyboard pressing member 43 a blank piece of molded plastic may be substituted so as to fill the space otherwise occupied by the member 43 and to provide a generally smooth upper surface to the handle member 14.

The construction and arrangement of the parts here described and illustrated provides improved results in an advantageous and economical manner.
